The term “seamless” gutter is actually a misnomer for “continuous” eavestrough. When first developed, the portable roll forming equipment we now call gutter machines were described as seamless roll formers.
This description came from the idea that standard sized roll of aluminum gutter coil could form up to 1,000 feet of eavestrough at one time. As no residence had need for any gutter nearly that long, the term “seamless” was coined.
If you have ever walked out of your home and been drenched at the door, you thought about eavestroughs. If you have installed costly landscaping, only to see it wash away after the first rain; or if you have unsightly stains on your siding or brick, you have thought about eavestroughs. If you have cracks in your walls, floor, or ceilings; or your house is 8″ lower at the back door than at the front entrance due to settling and foundation problems, you have given a lot of thought to eavestroughs. Improper drainage around your home can be unsightly and extremely costly. Do not be reluctant to invest between 1/2 percent and 1 percent of the cost of your home in a drainage system. It’s the best investment you’ll ever make.
There are various types of rain carrying systems: Copper, Galvanized Steel, Painted Steel, and Painted Aluminum are the most well known. Copper is the heaviest and most expensive. Aluminum is the lightest and least expensive.
